无法获取行号

Question

我在一个包中有这个代码：

    BEGIN
      IF user_status_i = 'all' THEN
        OPEN l_get_data FOR

        SELECT 
           row_number() OVER (ORDER BY u.us_fullname) rn,

                 LEFT OUTER JOIN av_attrvalue a11 
                     ON a11.AV_TOKEN = 'USER:'||u.US_ID AND a11.AV_AP_ID='InSign' AND a11.av_at_id = 'Line5'

WHERE rn BETWEEN (pageN_i * records_i) - records_i + 1 AND (pageN_i * records_i);



      END IF;

我正在尝试获取行号，但是当我执行它时，我遇到了2个错误：

Error(1323,5): PL/SQL: SQL Statement ignored

和

Error(1361,14): PL/SQL: ORA-00904: "RN": invalid identifier

我从昨天起就一直在与此作斗争，我确信有一些我不知道的小事

您需要将其作为一个块才能工作，因为在同一个块中无法访问别名。

别名rn在同一语句范围中不可用。您需要使用派生表，如下所示

           a11.av_value as line_manager_5, u.us_flags, a12.av_value as business_unit,
